2 Claims. '(01. 143-43) This invention relates to a portable timber cutting apparatus, the general object of the invention being to provide a device, power driven,

and so constructed and arranged that one man can readily move the device into position to cut down trees and to saw the felled trees into the desired lengths as the trees.

This invention also consists in certain other features of construction and in the combination well as to cut brush around and arrangement of the several parts to be hereence will be had to the accompanying drawings.

wherein like characters denote like or corresponding parts throughout the several views, and in which: I

Figure 1 is an elevational view of the apparatus showing the saw in vertical position.

Figure 2 is a front view of the apparatus.

Figure 3 is a top plan view thereof showing the saw in vertical position in full lines and in horizontal position in dotted lines.

Figure 4 is a section on the line 4-4 of Figure 1.

Figure 5 is a section on the line 55 of Figure 3.

Figure 6 is a perspective view of the saw carrying handle.

In these views the numeral I indicates a frame of inverted U-shape, the ends of which support an axle 2 having the wheels 3 at the ends thereof and arms 4 slope upwardly and rearwardly from said ends of the frame and connect with the ends of a cross piece 5. 'A platform 6 extends longitudinally and has its ends connected with the bight of the frame I and the cross piece 5 and this platform supports a motor'M which is preferably air-cooled as shown. A hearing member I is carried by the bight of the frame I and a second bearing member 8 is carried by the cross piece 5 and a long shaft 9 passes through the bearing members I and 8 for rotary movement. Stops ID are carried by the shaft 9 and engage the bearing members I and 8 to prevent longitudinal movement of the shaft 9. The rear end of the shaft has connected therewith a handle bar II and its other end is formed with a tubular bearing forming member l2 for the shaft l3 of the saw l4 which is of circular form. The opposite end of the shaft l3 carries the V-pulleys l5 over which the V-belts l6 pass and these belts also pass over a pair of small V- Brunswick, 6a., a

pulleys I! on the shaft of the motor so that when the motor is in operation the saw is rotated as will be understood.

A rod I8 is slidably supported by the ears 19 on the rear portion of the-shaft 9 and a spring 20 has one end bearing against the rear ear I9 and its otherend against a washer or stop 2| on the rod l8 so that the spring tends to hold the rod [8 in a forward position with one end engaging either one of a pair of holes 22 formed in the bearing member 8 as more clearly shown in Figure 5.' The rear end of the rod is bent to form a handle 23.

As will be seen when the front end of the rod I8 is in one of the holes the shaft 9 will be in a position to hold the saw in a vertical position and when the shaft is turned and is held in this turned position by the rod l8 engaging the other hole 22, the saw will be in a horizontal position as shown in dotted lines in Figure 3.

When in horizontal position the device can be used to cut down trees, brush and the like and when in a vertical position the saw can be used to cut the trees into suitable lengths.

The device is so constructed that it can be .readily handled by one man so that it can be pushed forwardly to a point adjacent the tree, with the saw in horizontal position and preferably the device is positioned adjacent the tree and then the handle moved so as to move the saw sidewise against the tree, during this movement the device pivoting on the wheels. Also, the saw can be made to out several cuts side by side in the tree to form a notch an inch or two wide on one side of the tree and then the device is moved to the opposite side to make a single cut slightly higher on the opposite side until the tree begins to fall. In this way the tree can be caused to ,fall in any direction desired to avoid destruction of small timber and so forth. However, it will, of course, be understood that the device can be used in any way the operator sees fit. After the tree has been felled the saw is turned to a vertical position and then used to saw the tree into lengths. The device can also be used in a horizontal position to cut brush so that the device can readily approach the tree to be felled and the engine should be of such size and power that if the saw should become stuck in the tree the engine will choke and thus the blade or parts of the apparatus will not be injured.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In a device of the class described, a frame including an inverted U-shaped part, a shaft carried by the ends of the limbs of said part, wheels carried by the ends of the shaft, said frame also including a rear part and members connecting the rear part with the U-shaped part, a platform supported by the upper portion of the U-shaped part and the rear part, a motor carried by the platform, bearing members carried by the upper portion of the U-shaped part of the frame and the rear part, an elongated shaft passing through the bearing members and supported therein for rotary movement, a handle on the rear part of the elongated shaft, a transverse bearing member connected with the other end of the elongated shaft, a saw shaft journaled in the transverse bearing member, a saw at one end of the shaft, pulley means at the other end thereof, pulley means on the shaft of the motor, belt means connecting the pulleys together and latch means for holding the elongated shaft either in position with the saw in vertical position or said saw in horizontal position.

2. A portable saw comprising a frame including a depending front part and a horizontal part extending rearwardly from the front part, wheel carrying spindles extending outwardly from the lower end of the vertical part of the frame, an elongated shaft having an intermediate part journaled on the horizontal'part of the frame with a front portion of the shaft extending well beyond the wheels and a rear portion extending well beyond the rear end of the horizontal part of the frame, a handle connected with the rear end of the shaft, a bearing member connected with the front end of the shaft and extending at right angles therewith, a saw shaft rotatably arranged in the bearing member, a saw connected with one end of the saw shaft, a motor on the horizontal part of the frame spaced rearwardly from the vertical part of the frame, drive means between the motor and the saw shaft and latch means for holding the elongated shaft in a position, with the saw vertically arranged or with the saw horizontally arranged, such latch means including an actuating part located adjacent the handle of the elongated shaft.
